Get the value of a JSON Array C# using Json.Linq

Question

I like to get the first value of JSON array.

My JSON:

{
    "userlist": [
        {
            "id": 123,
            "name": "Max",
        }
    ],
}

What I have:

public int JSONId(string JSONstring)
        {
            JObject responseJSON = JObject.Parse(ResponseGETSearchForCorrectID);
            int id = (int)JArray.Parse(ResponseGETSearchForCorrectID).Children()["userlist"]["id"].First();

            return id;
        }

But I get this error: Newtonsoft.Json.JsonReaderException: 'Error reading JArray from JsonReader. Current JsonReader item is not an array: StartObject. Path '', line 1, position 1.'

I tried also:

int idPackage = responseJSON["userlist"]["id"].Values;

But doesn`t work too because I get an exception with the info, that this is an array.

What I do wrong here? Have someone a soulution?

Thank you.

I edited and made the JSON file shorter to understand more easily. There is more stuff after ] but thanks for the info — bmw_58

Try it this way

int idPackage = responseJSON["userlist"][0]["id"].Value<int>();

Since userliat is an array, you have to access the objects via index.

Try this way:

var obj = JsonConvert.DeserializeObject(str);
int id = obj.userlist[0].id;
